If you're anxious about the holidays, strap on the rather tepidly named Rationalizer to monitor your stress levels so that you can avoid flipping out in front of the fam (again). From Physorg.com:
The Rationalizer consists of an "EmoBracelet" and an "EmoBowl" and incorporates sensors and signal processors designed by Philips. The EmoBracelet's galvanic skin response sensor measures the level of emotional arousal in a similar way to a lie detector. The result is displayed on either the bracelet or the EmoBowl as a light display that intensifies and changes to reflect the wearer's intensifying emotional arousal. At the highest emotional stress level the display has a greater number of elements moving at higher speed, and the color changes to a warning red.
